I use vim ;-).  But I am a very basic user, I don't know much on vi.  I can 
use emacs, though, it is much more intuitive than vi, but still I prefer
vi...

I tested with your tricks, and in my tests, the ^A is kept as is:

echo "int main() { }" > aa`printf '\x01'`bb.h
echo '#include "aa'`printf '\x01'`'bb.h"' > inc.c

And look at
cpp inc.c

or
gcc -E inc.c

And gcc compiles the file ok.

So, what to do now?  Keep things as is, report a bug to cpp?
